Bug Description

Please allow for setting gsettings keys for both a phone and tablet background (more appropriately a landscape and portrait background), and then automatically choose the most appropriate background based on native screen aspect ratio

The topic was discussed on IRC, it seems a better approach would be to keep using the keyring background key, just set it to whatever background is appropriate for the device on first boot (e.g we just need some snippet doing the ratio calculation and writting the key)
